Question

If a gene is found only on the X chromosome and not the Y chromosome, it is said to be what?

codominant trait
sex-linked trait
incomplete dominance trait

Answer 1

Answer:

Sex-linked trait

Explanation:

When a gene is present on the X chromosome, but not on the Y chromosome, it is said to be X-linked. X-linked genes have different inheritance patterns than genes on non-sex chromosomes (autosomes). That's because these genes are present in different copy numbers in males and females.
